Big Bend National Park’s river ranger Mike Ryan is passionate about working to conserve the river for future generations. Growing up less than five miles from the river, Ryan has long appreciated its charm, power and role in sustaining life. As a park ranger, Ryan is primarily responsible for law enforcement and protecting Park visitors. However, he spends whatever extra time he can find assisting the Park’s and partnering scientists, conservationists and managers as they restore the river after decades of decline.

Known locally as El Cabezón de Julimes, several thousand pupfish take up exclusive residency in El Pandeño de los Pandos hot springs in this small municipality about 80 minutes southeast of City of Chihuahua, Mexico. Rarely more than two inches long, pupfish live in water that reaches 114 degrees Fahrenheit, earning it the title of “hottest fish in the world.”

This involves removing invasive plants that threaten the natural environment, re-vegetating tributaries that fuel the river, and coordinating crews to help with all these processes.
